DIRECT WARPING AND BEAIVIING MACHINE.

Specification of Letters Patent.

Application filed February 14, 1919; Serial No. 277,060.

To all whom it may concern.

Be it known that I, JOHN H. BENTLEY, a citizen of the United States, residing at Midland Park, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Direct Warping and Beaming Machines, of which the following is a specification.

This invention relates to machines whereby threads are drawn from spools on a creel or other source of supply and made into a warp and beamed, and it consists in certa n improvements whereby the necessary operations are performed without undue strain on the threads and yet so that they are kept always under tension, and as nearly as possible under uniform tension, and so that they shall he so distributed on the beam as to prevent them cutting into the previous windings, and whereby an improved quality of product will be turned out and the operation simplified and made to require the employment of less skilled attendants than heretofore.

In the drawings,

Fig. 8 is a side elevation of a part of the creel; and

Figs. 9 and 10 illustrate the stop motion means.

On the frame a is arranged a U-shaped stand 6 in which and another stand 0 is journaled a horizontal shaft 03 on which are arranged a cross-head c and a fiy-wheel f, the

former being fixed to the shaft and the latter revoluble thereon, there being cushion springs g interposed between the arms ofthe cross-head and projecting lugs it on one face of the fly-wheel. ble on the shaft, has a stud j to implnge against some projecting portion of the fly- A pulley freely revolupulley 2' or from the latter onto the pulley 7c,

and when the former of these movements is effected the pulleys coact after the manner of a friction clutch, so that the pulley 2' picks up gradually; for this purpose they preferably have broadened coacting friction surfaces as indicated at n in Fig. 2. When the belt is shifted from pulley is to pulley 2' in starting up the slip friction at n and the elastic cushion afforded by springs g insure the strain being imposed on the warp (the advance of which it will be explained is frictionally opposed) gradually, so as not to stretch it unduly and possibly cause disruption of some of the ends or threads. Backward rotation of the shaft is prevented by a ratchet-and-pawl indicated at o, the ratchet serving as apart of the means to hold the shaft against longitudinal movement.

Between the stands 6 and c, the latter of which is removably secured in place to the frame a by the clamp c, the shaft (Z is squared, and its squared portion is adapted to receive a felt roller 10 which may be applied thereto or removed therefrom upon removing the stand 0.

The beam is indicated at g, the same preferably consisting of a barrel on which the windings or warp are placed and flanges or heads 9, The beam rests with its barrel superimposed on the felt roller 39, its flanges receiving the latter between them and so confining the beam against longitudinal movement. The beamis held superimposed upon the felt roller by a holder consisting of a pair of veritcal rods 1', which are guided in a bracket .9 for movement in a vertical plane, and a U-shaped head r afliXed to the upper ends of said rods and having downwardly open hearings to receive the trunnions g of the beam. By this construction, the angle at which the warp comes to the beam remams constant, as well as vance-of the warp (so long as the speed of the rate of adthe felt roller is constant), notwithstanding the effective diameter of the wound acking increases as the windlng proceeds.

I justable The warp, designated A, extends through the usual condensing reed t and is then made subject to the usual cross-forming means a before being wound on the beam, the means 2 and a being carried by an elongated bracket U attached to the frame 01..

Between the cross-forming means a and the beam I interpose means to cause the warp as it is wound on the beam not only to traverse laterally back and forth but to do so in such manner as to insure perfect crossing of the threads and their being so distributed as to prevent the threads cutting into the previous windings. By means of a clamp to an inverted U-shaped fitting as is secured in the bracket 4) so as to be adon an axis parallel with that of the beam. This fitting has an upstanding stud 3 receiving a depending socket 2 (having a set-screw 2 to secure it to the stud at any desired elevation) attached to the cross-bar 3 of a frame which includes with the crossbar a pair of vertical guides 4:. These guides penetrate the upper and lower bars 5 of a reed whose dents 6 are parallel and are each formed with intermediate portions 6 displaced laterally with reference to their ends, as by forming V-shaped bends therein. A horizontal felt roller 7 is journaled in uprights 8, secured to the frame, fairly close to the reed, but preferably not so close but that there will be at the reed more or less of a space between the plane occupied by the upper and that occupied by the lower set of threads as they are held separated by the nearer bar a of the cross-forming means. The frame may be adjusted vertically at 2, and the whole structure, including the fitting, may be shifted toward and from the beam on the axis of the fitting. Reciprocating vertical movement is imparted to the reed from cranks 9 on a horizontal shaft 10, 'ournaled in the frame, through the medium of links 11. The-shaft 10 is rotated from shaft 03 by a pulley 12 on shaft d and a belt 13 extending around this pulley and a pulley 14 on a shaft 15 journaled in a bracket 16, a pulley 17 on shaft 15 and a belt 17 extending around pulley 17 and a pulley 18 on shaft 10. An important element of this part of my invention is the roller 7 placed in close proximity to the reciprocating reed and bearing against every thread in the warp (preferably so as to displace the same slightly out of the plane which it tends under tension to assume between the crossforming means and the beam-Fig. 3) the roller or its equivalent holds every thread at a definite elevation though the reed might tend to displace it up or down, this insuring the threads accurately and certainly responding to the displacing action of the reed and so being distributed in a uniform and certain manner by-the reed over the surface of the package being wound.

As the reed reciprocates and while it moves in either direction first one and then the other of the two sets (upper and lower) of warp threads is shifted laterally and back, in consequence of which as they are wound on the beam the threads are traversed and there is a crossing of the threads due not only to this traverse in connection with their winding on the rotating beam but in fact to one set of threads moving laterally, one way while the other set moves the other way as the former proceed to the summits or bends 6 while the latter are departing therefrom.

The warp threads A are taken from supply spools 19 journaled on skewers projecting at an incline from a creel 20 in the usual manner. The relatively lower face or end 22 of each spool bears against a felt strip 23; there may be one such strip for every row of spools. This strip affords frictional resistance to the rotation of the spools so as to impose desirable tension on the warp and so that when the power is cut off by shifting the belt Z from the pulley i to the pulley 7c the spools will not overrun and cause any slackening of the tension, which in a good warp should be as near as possible uniform from start to finish. After passing through the usual reed 24.- on the creel each thread encounters a stop-motion mechanism constructed as follows: A bracket 25 on the creel supports a pair of parallel horizontal rods 26 insulated from each other and forming the terminals of an electric circuit 27 which may include an alarm device 28 and a breaker 29. On the upper rod 26 are fulcrumed a series of fallers each composed of a wire 30 formed with a loop 31 to afford its bearing portion and having one arm formed with a bend 32 affording an upwardly open downwardly converging thread notch 33; the other arm of the faller is the heavier, as by being the longer arm, and tends to hold the faller in the dotted line position of Fig. 8. The thread notch affords, facing relatively laterally and oppositely, thread bearing surfaces 34: (Fig. 10) so disposed that in order for the taut threads to pass from the bar 24 to the reed t it must suffer slight deflection. The object of this is to distribute the wear of the threads on the faller more or less over the sides of the notch, it being found that if the thread bears against the lower end of the notch it forms an undesirable nick therein; it will be understood that when the warp is advancing each thread causes slight vibration of the faller, insuring the distribution of the wear as stated. If a thread breaks, the faller assumes the dotted line position and by closing the circuit operates the alarm device 28.

The amount of yardage beamed may be calculated by means of the clock shown in Figs. 2 and 3. An upright 35 projects from the stand I) and supports a bell 36 and affords a bearing for a worm-whee1 37 having a stud 38 to engage a hammer mechanism 39 for the bell. The worm-wheel is in mesh with the worm 40 journaled on the shaft (Z and connected with said shaft by the gearing 41.

When the machine is started up, by establishing the disconnective connection at n on shifting the belt m from pulley 7a to pulley 2', the strain is imposed gradually on the warp threads because of the slip-friction at a and the elastic cushion afforded by springs g, as explained. When the power is cut off, by shifting the belt m to pulley 7c, the momentum of the fly-Wheel keeps it running and the warp advancing somewhat after the connection at n is disestablished and this, taken with the braking resistance offered to the spools by the felt strips on the creel, insures the tension being kept up on stopping to substantially the degree it was while running, in consequence of which the tension of the warp remains as nearly as possible uniform from start to finish. When a beam is full, the operator can readily replace it with. an empty beam by raising the holder 9 r in its guiding means 8. The structure including reed 6 and guide 7 is shiftable pivotally in arm .2) so as to permit the reed to be brought to the proper angle with reference to the warp and yet permit these parts to be moved out of the way when changing beams or performing similar operations.

Having thus fully described my invention,
